invention to provide an apparatus for determining the amount "of gasolene carried in natural gas.

J As-well known, natural gas contains gasolene in varying amounts. The gasolene is extracted from the gas by various means such as condensers or absorptionapparatus.

In the latter the natural gas is made to contaot intimately with an absorbing menstruum,such as hydrocarbon distillate,fr0rn which it'is later recovered by suitable means. It is desirable to ascertain from time to time the amount of gasolene contained in a certain volume of natural gas and there are devices whereby the percentage of gasolene carried by natural gas is determined. The objection to the devices now in use is thatit requires considerable time to make the test and unless the same is carefully performed the results are unreliable. Furthermore,'even when accurately made, the tests do not correspond with the amount of gasolene recovered by the commercial methods now in use.

The object of this invention is'to provide a simple apparatus whereby a test can be quickly made without the necessity of careful manipulation and where the result of the test can be immediately read from the meter or gage of the apparatus. Furthcrmore, the principle of extraction employed in the device is the same as the commercial absorption method which is the one now in that the test corresponds very closely with in the plant.

My invention consists in the construction, combination and arrangement of parts hereinatter described and claimed.

In the accompanying drawings which form a part of this specification Figure 1 illustrates an elevation of my apparatus with parts in vertical cross section. Fig. 2 is a verticalsectional view on an enlarged scale of the gas pressure regulator. Referring to the drawings, 10 indicates the gasoleuc testing apparatus. The same pipe or flexible 30 in a water container consists of a suitable base'll, on which a vertical cylinder 12 is secured by means of a flange ring H graduated glass tube 13 tion with the-lower end of by means of an elbow 14' tapped therein, the

upper open end of the glass tube 13' being held by a bracket 15' mounted on the cylinder. A short upright cylindrical tube 16 of comparatwely small diameter is mounted on the base 11 concentrically with the pipe 12 and is provided at its lower end with radial apertures 17. Tapped through the base 11 and terminating at the center of the mixing tube 16 is a gas nozzle-18 connected by means of a pipe 19 in communication with a gas casing 20. i has a reducing bushing pipe 22 leads to a gas pressure regulator 23, 24 is a valve in the pipe 22 and '19" is a valve in the pipe 19 communicating with the gas ressure regulator 23. The function of the gas pressure regulator 23 is to reduce the gas pressure to a predetermined degree, and any other suitable gas pressure regulator may be substituted therefor. In the present case the gas ress'ure regulator 23 consists of a T connection 24, one horizontal end being connected with pipe 22, and the other end being connected with a coil of hose 30 which is joined to pipe 19. In order to control the temperature oft-he gas I place the pipe or hose coil 31 having a valve water inlet pipe 32 and an overflow pipe 33. The temperature of the gas may be easily controlled by controlling the cold water inlet to the tank 31.

In the vertical arm of the T connection 24 is a cylinder 25 screw threaded therein. The cylinder 25 is open at its upper end and provided intermediatev its length with vertical slots 26. A plunger or. gas ing cylindrical heads 28 at opposite ends and areduced intermediate portion 29 its slidingly in the cylinder25: audvwhich, as the gas pressure exceeds a predetermined degree, uncovers the 'slots 26, thereby affording escape to the excessive gas pressure. f In the operation of the device the cylinder 12 is filled with a gasolene absorbing oil or hydrocarbon such as seal oil, which is a neutral mineral oil slightly yellowish, of 35 B6", or any other low grade distillate. I prefer to take 125 c. c. of the absorbent oilaud pour the same The gas casing 20 21 from which a deo resembling kerosene,

absorbent oil into 'intothe cylinder 10, after closing the valve accurately determined by any preferred method, through the absorbing oil at a pre. pressure, say 89 inches of Water determined pressure at a temperature of 80 F. for half an hour. The gas in leaving the nozzle 18 Will bubble through the absorbent oil. The mixing tube 16 provided with perforations 17 will cause a circulation of the oil, thereby causing intimate contact'of the gas with the absorbent menstruum. I

It should be noted at this point that the agitation of the oil Will cause the lighter as pentane and butane, to volatilize and leave the oil so that the gasolene retained by the oil will correspond gasolene retained It has been found that an increase in volume of 1c. 0. of the absorbent oil, due to th absorption of gasolene, corresponds to 1 pints per thousand feet o1 gas.

.Assuming that the gasolene content of the gas used by calibrating the tester contained 1 gallon or 8 pints of gasolene, the level of the oil in cylinder 10 Will rise, Which rise Will correspond to the rise-in the glass tube 13. 'This point is marked as 8 pints and the glass tube between 8 pints and the mark zero is graduated to indicate points and fractions of points. The same graduations are extended above the point marked 8 pints.

The instrument being calibrated as just described, it is now ready for testing any other gas for its gasolene content, and all that is necessary is to place 125 e. c. of the the cylinder 10 and to run. the gas for the same period of time, 30 minutes, at the same pressure, 12% inches, and
